As a first embodiment:

as shown in fig. 1, 8, 11, 16, and 17, a liquid inlet 204 is disposed on the valve body 2, a fixing sleeve side hole 407 communicated with the liquid inlet 204 is disposed on the fixing sleeve 4, a liquid storage cavity side hole 507 is disposed opposite to the liquid inlet 204, when the liquid is poured, the liquid storage cavity side hole 507 is located on the upward side of the connecting sleeve 4, and the liquid inlet 204 is located on the downward side of the valve body 2; the lowest position of the loading port 204 may be always lower than the liquid level of the reservoir 506, which facilitates the liquid in the reservoir 506 entering the damping chamber 206 through the loading port 204 or the side hole 407 of the fixing sleeve.

as shown in fig. 4, preferably, the lower part of the connecting sleeve 5 is provided with an elbow 504, the end sleeve 6 is arranged below the elbow 504, the circumference of the side surface of the end sleeve 6 is provided with a third annular outer buckling position 602, the inner wall of the elbow 504 is provided with a third annular inner buckling position 502, and the third annular outer buckling position 602 is in interference connection with the third annular inner buckling position 502; preventing the end sleeve 6 and the elbow 504 from rotating relative to each other; the elbow 504 is communicated with the connecting cylinder 505, the included angle between the axis of the elbow 504 and the axis of the connecting cylinder 505 is less than 90 degrees, and the end sleeve 6 is arranged below the elbow 504.

when the included angle between the axis of the elbow 504 and the axis of the connecting cylinder 505 is 0 °, the elbow 504 increases the length of the damping chamber 206, so as to increase the time for the ball 8 to roll to the ball sealing seat 205, thereby closing the liquid inlet 204 in a delayed manner.

As shown in fig. 1, 2 and 4, when the angle between the axis of the elbow 504 and the axis of the connecting cylinder 505 is acute, the offset direction of the elbow 504 is away from the handle of the container 12 when the dispenser is connected to the container 12 containing the solution; when the distributor is vertically placed, the sphere 8 is positioned on the sphere 8 limiting seat 603 at the upper end of the end sleeve 6 and is limited by the end sleeve 6; as shown in fig. 1, when pouring liquid, the container 12 and the dispenser are inclined in the opposite direction of the inclination angle of the axis of the elbow 504, when the axis of the elbow 504 does not reach the horizontal position, the liquid in the container 12 is replenished to enter the damping cavity 206, the ball 8 is kept still, the container 12 is continuously inclined until the axis of the elbow 504 is positioned at the horizontal position, the ball 8 starts to slide, enters the adjacent damping cavity 206 and slides along the damping cavity 206 to the liquid outlet 202 at the upper part of the valve body 2 under the action of gravity, and the liquid enters the liquid outlet pipe 201 through the liquid inlet 204 on the valve body 2 and flows out of the liquid outlet 202; when the ball 8 descends in the damping cavity 206, the liquid in the damping cavity 206 is balanced with the liquid in the container 12 through the balance hole 601 at the center of the tail end of the end sleeve 6; when the ball 8 descends to the ball 8 sealing seat 205 above the liquid inlet 204 and contacts with the ball 8 sealing seat, the ball 8 blocks and seals the damping cavity 206 and the liquid inlet 204 and the liquid outlet cavity 207, and liquid outlet stops; the elbow 504 delays the ball 8 entering the damping chamber 206, and further delays closing the inlet 204, so that when the liquid has poor fluidity, the container 12 has a large volume and the liquid pouring speed is slow, or the liquid storage amount in the container 12 is small, the relative stability of the pouring amount can be effectively improved.
